Video/Audio pauses on TNT

I've noticed over the past several weeks brief pauses (couple of seconds) of audio/video on TNT during the NBA playoffs. I've got a TiVoHD with the 1TB drive which I put in a couple of years ago I guess (back around the time that Costco had marked these units down for closeout). I'm trying to decipher if it is my FiOS feed from TNT or if it could be an early indicator of HD failure. The easy route obviously is for others to say that they've seen the same as well. I've got images as well as the original 160GB drive but if it were to be the HD (caps looked ok just a couple of months ago) it might be time to play with one of the Crucial 256GB SSD's since I'm running one in my laptop and I no way take advantage of the 1TB space.

It is noted more with TNT since I've been watching that channel for the NBA games recently but the infrequent instances that I note it with others is so infrequent that I don't associate it as being an issue. I do suspect TNT/FiOS but was curious to see if others who have been watching the games had noted the same. If it were a TNT/FiOS issue then I would expect others to reinforce the same finding.
